Study Progress of the Activation of Granulated Blast Furnace Slag Cementitious Material

Abstract

Abstract: The granulated blast furnace slag is a kind of amorphous glassy structure material, it's chemical composition is quite similar to the silicate cement clinker, and has the potential cementitious activity. This paper analysed the characteristics of the composition and structure of the granulated blast furnace slag, elaborated the reason and influencing factors of the cementitious activity. The paper focused on some activation method of the slag and the progress we've made. And summarized the understanding of the hydration mechanism of the slag now.

Key words: Granulated blast furnace slag, Cementitious material, Mechanical activation, Chemical activation, Hydration mechanism
